Issue with downloading from itvplayer

[tqmartini]

Hi!
I have an issue with itvplayer which I can't solve since a few hours... I want to get this video https://www.itv.com/itvplayer/lorraine/14-02-2014

I tried rtmpsuck and rtmpexplorer but nothing (the second one is able to sometimes catch first ad) I used URL snooper and got that

rtmpe://cp72511.edgefcs.net/ondemand?auth=eaEd3b_aTcIc6b.dSauakdcbLdJd7d8a9bxbcdYb9awcQaBaWdaanc4aEa5bZchcSaj-bs_HKi-eS-9yp1HCrlDsys&aifp=v002&slist=production//mp4:production/priority/rtmpecatchup/800/1B/1-9360-1072-001/1-9360-1072-001_lorraine-(2014)_tx140214_itv800_16x9-reg.mp4?sessionId=27CBEBCD-BEE5-AD12-5E79-34ABC8B7D4E8

and turned it into:

rtmpdump -r "rtmpe://cp72511.edgefcs.net/ondemand?auth=eaEd3b_aTcIc6b.dSauakdcbLdJd7d8a9bxbcdYb9awcQaBaWdaanc4aEa5bZchcSaj-bs_HKi-eS-9yp1HCrlDsys&aifp=v002&slist=production/" -W "https://www.itv.com/mediaplayer/ITVMediaPlayer.swf" -y "mp4:production/priority/rtmpecatchup/800/1B/1-9360-1072-001/1-9360-1072-001_lorraine-(2014)_tx140214_itv800_16x9-reg.mp4" -o x.flv

but rtmpdump simply opens and closes right away...

Could someone tell me what am I doing wrong all the time?
Thank you,
tq
